Mitsubishi Materials Corporation has added newly developed LM/MM breakers for 7° positive insert and 5° positive insert to PVD Coated Carbide Grade for Stainless Steel Turning "MP7035". This series will start to be sold by Mitsubishi Materials Tools Corporation (President: Toshio Takizawa, Headquarters: 1-6-1 Yokoami, Sumida, Tokyo).
Stainless steel has been used in various fields such as for household goods, building parts, automobile parts and chemical industrial parts. Stainless steel has low thermal conductivity, tends to be sticky and is subjected to work hardening, thus leading to the following problems:
1) It is prone to lower the tool life due to plastic deformation of the cutting edge, 2) It is prone to have abnormal damage due to welding, 3) It is prone to form burrs due to major flank notch of depth of cut.
It is therefore well known as being difficult to machine.
To address these problems, newly developed LM/MM/RM/GM breaker for stainless steel turning and new grades; MC7015/MC7025 (CVD coated carbide grade)/MP7035 (PVD coated carbide grade) were released at December 2012. Moreover, 134 items were added to the insert series for stainless steel turning at April 2013.These series make it possible to carry out stable machining to cover a wide range of different machining applications that lead to improved productivity. Thus these items are highly commended by customers.
To allow wider range of applications, LM/MM breakers for 7° positive insert and 5° positive insert have been added to PVD Coated Carbide Grade for Stainless Steel Turning "MP7035". Therefore, "Insert Series for Stainless Steel Turning" have been expanded.
